Description

[Detailed description of the invention] The invention relates to transparent fabrics.

More specifically, the present invention relates to a fabric having excellent transparency and high clarity.

Recently, fabrics, especially cloth hangers for women's clothing, are no longer satisfied with the primary purpose of concealment, body surface, etc., and there are signs that they are becoming more fashionable.

Particularly, the parts that make your skin look beautiful, Waittoko Foundation V
There is a tendency for greater transparency to be desired in fields such as yongs, lingerie, and stockings. Conventionally, attempts have been made to satisfy these requirements by, for example, reducing the total fineness of the fibers used, or reducing the number of single yarns while maintaining the same total fineness. However, in the former case, there is a problem in terms of the strength of the fabric, and in the latter case, there are disadvantages such as reducing the number of single threads and damaging the flexibility of the tangled fabric. A fabric with good properties could not be obtained.

The inventors of the present invention have made extensive studies to overcome the drawbacks of the conventional techniques, and have thus arrived at the present invention. Therefore, it is an object of the present invention to provide a fabric which has excellent transparency and excellent clarity without impairing its softness.

That is, the following general formula (1) or (2)
The bulky diamide compound is 0005-2. O7[j
The gist is that the polyamide fiber has a polyamide fiber having a tongue.
where n is a number of 1 to 10] The present invention will be described in more detail below.

The diamide compound used in this study C.3 has the structural formula shown in the above general formula (1) or (2).
'411J, and the stiffness can be prepared by the reaction of cicafreponic acid with an alkyl monoamine, or by the reaction of an alkylene diamine with 7kaleponic acid. Typical diamines include methylene diamine, ethylene diamine, globylene diamine, and butylene diamine, including alkylene diamines having 1 to 10 carbon atoms. Typical dicarboxylic acids include succinic acid, adipic acid, sepacic acid, and dicarboxylic acids having 2 to 12 carbon atoms.

Examples of alkyl monoamines include monoamines having an alkyl group having 10 to 20 carbon atoms, such as octadecylamine, methyloctadenylamine, ethyloctadenylamine, etc., and monoamines having alkyl groups of 10 to 20 carbon atoms, and 2-monoamines substituted with methyl or ethyl groups. Contains Ganpumin.

Monocarboxylic acids include alkyl monoamic acids having 11 to 21 carbon atoms, such as turic acid, palmitic acid, and stearic acid.

The polyamide fibers used in the present invention are wR fibers spun from linear molecules having amide bonds in their molecular chains, such as polyglypamide and polyhexamethylene adipamide.

Methods for adding the diamide compound of the present invention to polyamide fibers include adding it to the folded fibers when the polyamide is combined, and adding it to the polyamide fibers. Also, when these are bath-melt spun, it is important that the diamide compound is uniformly dispersed in the polyamide.

The amount of diamide compound added is u, o relative to polyamide.
, os ~ 2.0 dish volume% range (needs to be rubbed, 00
If it is less than 0.05 t%, the transparency effect will be small, and 2. O
If the amount exceeds the JM amount %, the compatibility between the diamide compound and the polyamide will deteriorate, resulting in a loss of transparency.

Of course, the object of the present invention cannot be achieved with amide compounds other than the general formulas (1) and (2) of IIJ, such as stearic acid amide and terephthalic acid amide.

By adding an unexplained diamide compound to polyamide and spinning it into fibers, the resulting fibers have a transparency of η. The effect is extremely noticeable.

The fabric here refers to fibers, knitted fabrics, or a combination thereof, and the fibers that make up the fabric include the diamide compound of the present invention. It is necessary that the added polyamide fibers be kept at least 10°C. Therefore, all of the fibers constituting the fabric may be the polyamide fibers of the present invention, or the fabric may be composed of other natural fibers, synthetic fibers, and the polyamide fibers of the present invention.

Hereinafter, the present invention will be explained in detail by giving Examples.

Example 1 0.3 liter of sulfuric acid relative viscosity 2.85 nylon 6
Add 1% ethylene bisstearic acid amide (Lion Akzo Roarmo Wax EES) powder, and
After mixing, the mixed blade was melted at 285°C, extruded through a nozzle with 6 L5 hole diameters, rolled up at a speed of 800 m7, and then drawn with A51 fit to form a 60 denier mulch with a single thread count of 6. I got the filament. Stearin amide, terephthalic acid amide and blank multifilaments were obtained in a similar manner.

A tube knit was knitted using a 9 mm cylinder with a cylinder diameter of 5 1/2 inches and 520 needles, and a feed yarn length of 50 inches/circumference. Table 1 shows the transparency evaluation results after kneading.

1st surface pressure 1a: Clarity evaluation was carried out at level 4 (16 vs. The transparency is extremely superior compared to conventional products.Also, compared to conventional products, this fabric has no disadvantages in terms of physical intercourse (in addition, the fabric is more flexible than conventional products). was.

Example 2 The fabric of the present invention (Level 1) and the conventional fabric (Level 4) obtained in Example 1 were dyed using a conventional method, and the brightness and saturation were measured using a spectrophotometer. Table 2 shows the measurement results for a fabric that was dyed under maroon conditions where the dye was changed once and the saturation reached the highest value for both levels.

I was aware of Table 2. Yurumachi yo kiunter chromaticity evil (this is a%bllt1).

As shown in Table 2, the transparent fabric (Level 1) has the same brightness, color saturation, quality, and dye clarity as compared to the conventional fabric (Level 4). I'm LL.
